COCK FOR WATER-COOLERS.

SPECIFICATION forming part of Letters Patent No. 498,366, dated May 30,1893.

Application filed January 28, 1893.; Serial No. 459,966- (No model.) I

T0 on whom it may concern.-

Be it known thatl, JOSEPH H. SAVILL, a citizen of the United States,residing at Philadelphia, in the county of Philadelphia and State ofPennsylvania, have invented certain new and useful Improvements in Cocksfor Water- Coolers; and I do declare the following to be a full, clear,and exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same.

My invention relates to improvements in that class of cocks, designedmore especially for use in conjunction with water coolers and the like;and it has for its general object to provide a simple, durable andcompact selfclosing cock, and one embodying such a construction thatbuta minimum amount of frictional wear will result from use, and whenthe same takes place it will not affect the efficiency of the cock.

Other objects and advantages of the invention will be fully understoodfrom the following description and claims when taken in conjunction withthe accompanying drawings in which- Figure 1, is a vertical, diametricalsection of my improved cock; the same being illustrated in position uponthe discharge pipe of a cooler. Fig. 2, is a detail elevation of thatside of the valve casing which rests contiguone to the cooler. Fig. 3,is a perspective View of the valve body or core removed. Fig. 4, is asimilar View of the valve, and Fig. 5, is a perspective view of thespout section.

Referring by letter to said drawings:-A, indicates a portion of a watercooler, and B, indicates the draw off pipe thereof which may form apermanent or fixed part of the cooler or of my improved cock, as is mostdesirable. In most cases the draw off pipe B, forms a permanent part ofthe cooler, and I therefore provide the outer end of the same withthreads a, designed and adapted to engage the threaded aperture 1), ofthe head 0, of my improved cock. This head 0, is provided with a chamberc, which communicates with the pipe B, and is also provided at one endwith an enlarged recess d, which communicates with the chamber 0, andserves to form the shoulder e,

which in turn serves to seat the valve as will be presently explained.

D, indicates the slidable or movable casing of my improved cock; Thiscasing which surroundsthe fixed head C, is provided with a longitudinalslot f, for the passageof the pipe B, and is also provided with a spoutE, or nozzle which is preferably connected in a detachable manner sothat it may be readily removed when desired to permit of an introductionor removal of the parts inclosed by the casing. The bore of the spout ornozzle E, is reamed out at one end as shown,so as to form moves with thecasing D. This valve F, which is hollow and is provided with thelaterally disposed apertures h, has aconoidal upper end as shown,whereby it will be seen thatit effectually prevent the passage of waterfrom the chamber a.

By reason of the peculiar formof the valve F, it will be further seenthat when the seat 2, has become worn and enlarged, said valve willextend farther into the chamber 0, and will thereby effectually closecommunication between the said chamber and the recess d.

G, indicates a spring, which is designed and adapted to normally holdthe head 0, upon the valve'F. This spring G, is interposed between theupper end of the head or movable seat 0, and the casing D, whereby itwill be seen that it will serve to hold the .casing in its normallyraised position and will also serve to raise the casing to such positionand the head or seat upon the valve, after the user removes his handfrom the head of the casing.

connection with the accompanying drawings it will be seen that myimproved valve is very simple, compact, and easily operated, and that ofthe parts which is a highly important desideratnm.

I have entered into a detailed description of the present embodiment ofmy invention, in order to imparta full andclear understanding of thesame, but I do not desire to be confined to the specific constructionand arrangement of parts herein set forth, as in the praca support orshoulder g, for the valveF, which From the foregoing description takenin will normally close light in the seat 6, and will its efficiency isnot affected by frictional wear tice of the invention, such changes ormodifications may be made as fairly fall within the scope of the same.

Having described my invention, what I claim is- 1. In a cock for watercoolers or the like, the combination of a head adapted to be connectedto a fixed discharge or draw-off pipe and having a chamber to receivefrom said pipe, a casing movable with respect to the head, a valvecarried by said casing and adapted to close the chamber of the head, anda spring interposed between the head and the casing, substantially asand for the purpose set forth.

2. In a cock for water coolers and the like, the combination with a headadapted to be connected to a discharge pipe and having a chamber toreceive from said pipe; of a casing movable with respect to the head,avalve carried by the casing and having a conoidal upper end adapted toclose the chamber of the head, and also having apertures for the passageof the water, and a springinterposed between the head, and the casing,substantially as and for the purpose set forth.

3- A cock for water coolers or the like comprising a head adapted to beconnected to a discharge pipe and having a chamber to receive from saidpipe, a casing movable with respect to the head and having a slot forthe passage of the discharge pipe, avalve carried by the casing andadapted to close the cham ber of the head, and a spring interposedbetween the head and the casing, substantially as specified. I p

In testimony whereof I affix my signature in presence of two witnesses.
